Working Principles

When an overvoltage event occurs, the SMBJ15CAHE3/5B TVS diode enters into conduction, providing a low-impedance path for the excess current to flow through. This effectively limits the voltage across the protected circuit, safeguarding it from potential damage. Once the overvoltage condition subsides, the diode returns to its high-impedance state, ready to respond to any future surge.

Detailed Application Field Plans

The SMBJ15CAHE3/5B TVS diode finds extensive use in various electronic systems, including: - Power supplies - Communication equipment - Industrial control systems - Automotive electronics - Consumer electronics

Its application extends to any circuit or device that requires protection against transient voltage events.

Detailed and Complete Alternative Models

• SMBJ15A: Similar specifications with a lower breakdown voltage
• SMBJ15C: Higher breakdown voltage and clamping voltage
• SMBJ15CA: Comparable characteristics with different packaging options

These alternative models offer flexibility in selecting the most suitable TVS diode based on specific application requirements.

In conclusion, the SMBJ15CAHE3/5B TVS diode serves as a critical component in safeguarding electronic circuits from transient voltage events. Its rapid response, high reliability, and compact design make it an essential choice for surge protection in a wide range of electronic applications.
